Abbreviation Question: "Esp" in 1756 Jerez Baptism Record

Hello!
I am reading and trying to understand what this abbreviation means in this baptism record. It looks like "Esp" and I am not sure what that is abbreviated for. I do see it in a few other records, but not a lot. Can anyone assist?

Here is the link to FamilySearch. It is on the bottom of the left side of the page for Joseph Bisente Roman, after it says his name "Joseph Bisente" and before the abbreviation for "son". I am thinking it is for illegitimate? But I am not sure.

Thank you all so very much!

Kristine
